The quick reply is that relating to flight instances and motor efficiency, the upper a battery’s C ranking, the extra probably it should make you smile. A 45C pack makes a joke of a 10C pack relating to energy supply. The C ranking for a LiPo battery, fairly merely, refers back to the capability of vitality the battery can safely discharge, represented as a a number of of its general capability. A battery that has the next C ranking delivers extra vitality, and meaning larger efficiency. The large distinction between batteries with completely different C rankings is the truth that the higher-rated batteries endure much less from voltage drops beneath load. This capacity to take care of the next and extra constant voltage is what usually generates the excessive efficiency we get pleasure from. That is significantly vital when you have got a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps repeatedly (10 instances 2000mAh equals 20 amps). A 20C pack of the identical capability will safely assist you to draw 40 amps from it repeatedly. That’s the identical capability and twice the amp draw. There are battery packs on the market rated at 30C, 45C, and even 70C that may ship (in our 2000mAh instance) 60, 90, and 140 amps. This main enhance in present permits us to run larger (or extra) motors in your multirotor for elevated length and/or payload-lifting capabilities. A better C discharge ranking offers us that additional “oomph” we get pleasure from in flight, irrespective of the airframe.
Though a pack with the next C ranking can typically be charged in much less time as a result of it could actually tolerate the next present charge, don’t be in a rush; you’ll be able to at all times cost it at 1C (one instances the capability), which can take about an hour for an entire cost. Doing this has produced the very best ends in our expertise; we now have some older packs that also function effectively after
a whole lot of cost and discharge cycles.
